Application filed mien a1, 1919. Serial No. 286,527.

To all whom it may concern Be it known that I, FRANK H. BLAKE, a citizen of the United Stairs, residing at Butte, in the county of Silverbow and State of Montana, have invented certain new and useful Improvenu-nts in 'lransmission- Bands, of which the following is a specification.

My invention relates to iillPlOVLlfiO-IliS in transmission or brake bands adapted for use in connection with the transmission gearing of Ford automobiles, while not necessarily restricted to this use.

An important object of the invention is to provide means whereby at least one of the ears, secured to the free end of the hand, may be removed therefrom, when it is desired to withdraw the band from the transmission oasing or introduce the same therein.

A further object of the invention is to provide a band of the above lllk'lltifllitld character which is simple in constriution, inexpensive to manufacture, strong and durable.

As is well known-tho Ford automobile. embodies planetary gearing and transmis sion bands are used in connection therewith. This gearing is arranged in a closed casing, havin a relatively small opening in its top. T \is small opening is normally covcred by a removable plate.

When it is desired to remove the ordinary transmission bands from this gear casing, great dlflioulty is experienced, and the gear casing is ordinarily taken apart. The forked ears secured to the ordinary type of transmission band are attached thereto by rivets, and to prevent the taking apart of the gear casing these rivets have to be out for the removal of the ear or ears. This operation is very difiicult and sometimes impossible to accomplish within the gear eas mg.

In accordance with my invention, I provide a transmission hand having an ea r detaahably that this end of the band will be free from obstruction and will permit ready removal of the band from the gear easing through the small opening, the opposite. end of the band carrying the other ear, which is passed through the small opening.

In the aa-ompanymg drawing forming a part of this specification:

The figure is a side elevation of a transmission band embodying my invention,

secured to one end of the same, so

parts being shown in longitudinal seriion for the purpose of illustration.

In the drawings, wherein for the purpose of illustration, is shown a )ret'erred embodiment. of my invention. tie numeral 5 dcsignates a metallic band. having a lining (i, of any Suitable tihrousmatrrial. The lining 6 is secured to the band 5 in the usual manner.

The numeral 10 designates the slotted or forked ears, detachahly st-curcd to the opposits end of the bum] llarh car 10 is carried by a base ll. which is preferably formed integral therewith. and this base is curved longitudinally. to con'la xt with the outer surfin'e of the band the same conforming to the curvature thereof. The. base 11 is provided with an outwardly and radi all) extending lug- 111 prciorably formed integral therewith, and adapted vfor insertion through an opening 13. formed in an outer metallic attaching strip 11. The lug 12 is held within the opening 13 hy a cotter pin 15 or like. device, passing through a transverse opening in the lug. The at" taching rip 14 is secured to the band hy rivets 1G or the. like. located a substantial distance. from the free end of the band. It ist-hus seen that the hand 5 and stri 14- provide a pocket therehetx oen, whie receives the base 11, which is in turn secured to the attaching strip 14 by the 111g 12.

"In placing the hand within or removing it from thr easing, the. car or ears 1.0 are removed, the attaching strips 14 being tonsioned to move in'win'dly for'eontaeting with the band 5 and conforming to the curvature of the same, thereby providing thin fiat ends. This enables either end of the band to be passed through the small opening of the transmission casing and about the drum of the gearing. \Vhen arranged within the, casing the tapered base. 11 may be passed into the pocket hetvccn the. band 5 and strip [4, the lug springing into the opening 13. when moved into registration therewith. The cotter pin 15 may then be inserted through the opening in the lug.

T have found that some degreoof success may he obtained by employing only one dotachable car 10 and associated elements soeured to one end of the band 5, the other end of the band having the usual ear permanently secured thereto.

It is to be understood that the form of my invention is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departranged upon one side of the band and se-- cured thereto and having a transverse opening) formed therein, a removable ear having a ase adapted for insertion betwccn the band and the attaching strip, a lug carried by the base and adapted for insertion within the transverse opening, and a conctin ear secured to the op osite end of the ham. 2. A transmissionand of the character described, com rising a band, an attaching strip arranged near one end of the band and secured to the outer side thereof at a point spaced a substantial distance from such end of the band, said attaching strip having a. transverse opening, a removable ear having a base adapted for insertion between the end of the band and the attaching strip and carrying a lug adapted to be passed through the transverse opening, means to hold the lug within the transverse opening, and a second ear secured to the opposite end of the band.

3. A transmission-band of the character described, comprising a band, attaching strips arrmiged near the ends of the hand and connected with the band at points remote from the ends of the band, said at taching strips being provided between their ends with openings, bases carrying ears and adapted for insertion between the band and the attaching strips, lugs carried by the bases and extending through the openings, and means to retain the lugs within the openings.

In testimony whereof I afiix my signature in presence of two witnesses.
